Answer

The part above the oxygen is a region of high electron potential and the hydrogens are low electronic potential.

Work Step by Step

Like there is lone pair on ammonia, there are lone pairs on oxygen. This region of lone pair is where the electron potential is higher and the hydrogens are where the electron potential is low. So the upper part is red and the part where there are hydrogens is blue.
